Anonaepestis

Taxonomic position: Anonaepestis tamsi is a species of moth belonging to the order Lepidoptera and the family Pyralidae (snout moths). It is a specialized pest that has co-evolved with plants of the Annonaceae family, posing a significant threat to sustainable fruit production in tropical and subtropical regions.

Host plants: The pest primarily targets trees within the genus Annona. Its main hosts include cherimoya, soursop, and sugar apple. Due to the high value of these crops, the presence of this insect can drastically impact the profitability of fruit farming operations.

Biology and life cycle: The life cycle consists of the egg, larval, pupal, and adult stages. Females typically deposit eggs on the surface of developing fruit. Once hatched, the larvae bore into the fruit, feeding on the pulp and seeds throughout their development. Pupation may occur within the fruit or in the soil, depending on the environmental conditions and the maturity stage of the host fruit.

Nature of damage and economic importance: Damage is characterized by tunnels bored into the fruit, which often leads to internal rot and premature fruit drop. The presence of larval frass on the skin of the fruit is a clear diagnostic sign of an infestation. High levels of pest density can lead to total crop failure, as the damaged fruit is completely unfit for fresh market consumption.

Control measures: Managing Anonaepestis tamsi requires an integrated approach:

• Strict orchard sanitation by removing and destroying infested fruit.
• Monitoring adult moth populations using pheromone traps to time interventions.
• Application of selective biological insecticides when monitoring indicates high risk.
• Implementation of quarantine protocols for the movement of fruit between orchards.
